3. ALL DIODES ARE TYPE 1N4003, EXCEPT AS NOTED.
2. ALL CAPACITORS IN MICORFARADS, EXCEPT AS NOTED.
1. ALL RESISTORS IN OHMS
NOTES: UNLESS OTHERWISE SPECIFIED.
Rev A to B
1. input ground balancing
2. earth ground relocated
3. bias transistors changed to Tip31's.
Rev B to C is first production
1. Speaker jack location moved to metal.
Rev D is first production
1. C182, C182, C184, C185 and equivalent on
locations on the other two channels were
converted to through hole caps.
Rev E add Speakons and "T" option.
